## What agents can do

- Help the user open the Zro website and navigate sign-up, sign-in, pricing, billing, and API key creation.
- Configure the user's local coding tool after the user provides or approves use of the generated API key.
- Use the existing inference API after setup.

## User-controlled steps

- Account sign-up and sign-in are user account actions.
- Billing and payment approval must be completed by the user.
- API keys are sensitive. Do not store a key except in the local tool configuration the user requested.
